Motorists across south Dublin are being urged to plan ahead as a fresh round of traffic restrictions, resurfacing projects, and local road closures affects journeys through Dún Laoghaire-Rathdown. This Dublin news update covers the main disruptions in place from late June into early July, including temporary speed limits, community event closures, and ongoing infrastructure works that could add delays on key routes.
The busiest impacts this week are linked to resurfacing, active travel upgrades, and long-running construction activity. For residents, commuters, and anyone who work in Ireland or travel regularly through the county, knowing where delays are likely can make daily journeys far easier.
Dublin news: Main traffic changes drivers should know
Several temporary speed restrictions remain in force across the area:
- M11 northbound: a temporary 60 km/h limit applies from the county boundary near Junction 7 to Junction 5 until 17 July 2026 to support resurfacing works.
- Wyattville Link Road westbound: a 50 km/h speed limit remains in place from Cherrywood Avenue to the Cherrywood M50 southbound slip road until 30 November 2026, or until works are completed.
These measures are intended to protect road crews and drivers while major works continue.
Road closures across Dundrum, Blackrock and Dún Laoghaire
A number of short-term and ongoing closures are also affecting local traffic:
- Kilmacud Road Upper, Dundrum: closed until 27 June for resurfacing linked to the Safe Routes to School programme

Where roadworks are causing delays
Beyond the closures, multiple locations are seeing road or footpath improvements, often with Stop/Go traffic controls or temporary lane restrictions during off-peak hours.
Key works are under way in:
- York Road, Dún Laoghaire
- Ballybrack Village
- Churchtown Road Upper
- Ballybetagh Road
- Killiney Avenue
- Frascati Park, Blackrock
Short-term works are also expected in Stillorgan, Shankill, Dundrum, Dalkey, and Deansgrange. Most activity is scheduled between 10am and 4pm to reduce peak-hour disruption.
Dundrum development and active travel projects
Construction activity has also begun at Dún Brí, the major housing development on the former Central Mental Hospital site in Dundrum. Enabling works, including demolition, utility preparation, and site setup, are now progressing. While most operations are staying within the site boundary, construction traffic is expected to increase gradually.
At the same time, active travel projects continue to reshape local routes. Ongoing works include the Dún Laoghaire Central Active Travel Scheme on Glenageary Road Upper and Mounttown Road, as well as the Dodder Greenway Ely’s Arch project. Safe Routes to School works are also advancing in Dundrum, Blackrock, and nearby areas.
